West Brom are the first Premier League side to concede as many as 13 goals after four matches of a season since Southampton in 2012-13.
While in Premier League action - coincidentally against West Ham - in October 2018, the 25-year-old sustained an ankle injury, a situation that would see him out of the club's first team until this season. We got through their lines a few times in the first half, but we couldn't get Jamie (Vardy) away.
The Foxes were without playmakers Dennis Praet and James Maddison for the clash with the Hammers at the King Power. Recent signings Wesley Fofana and Cengiz Under were included in the squad for the first time and both were on the bench.
Rodney Marsh has praised West Ham United duo Tomas Soucek and Declan Rice on Twitter for their performance against Leicester City on Sunday, while Darren Bent has raved about Michail Antonio on the social networking site.
Just when West Ham fans thought it couldn't get any better, Pablo Fornals picked out Jarrod Bowen to slot home a third.
Having won a free-kick when he was fouled by Caglar Soyuncu, Antonio made a well-timed run to the far post, where he headed home from Aaron Cresswell's pinpoint cross.
The mix-up between Ogbonna and Lukasz Fabianski resulted in a poor clearance from the goalkeeper which fell to Harvey Barnes, who sliced his volleyed attempt wide.
However, the Hammers' deep defensive line largely continued to deny the hosts space and they remained unsafe on the break through Antonio and Fornals.
Rice came close to making it 3-0 midway through the second half.
He shot from eight metres out, after holding off two defenders.
Bowen then put the icing on the cake with a clinical finish in the 83rd minute, courtesy of a defence-splitting pass by Fornals.
West Ham United celebrated a stunning 3-0 win at Leicester City in the English Premier League (EPL) on Sunday to end the Foxes' ideal start after three successive wins.
